struct FBodyInstanceCore
uint8:  1
bAutoWeld
If true and is attached to a parent, the two bodies will be joined into a single rigid body.
uint8:  1
bDirtyMassProps
Indicates mass props need to be recomputed when switching from kinematic to simulated
uint8:  1
bEnableGravity
If object should have the force of gravity applied
uint8:  1
bGenerateWakeEvents
Should 'wake/sleep' events fire when this object is woken up or put to sleep by the physics simulation.
TWeakObjectPtr<...
BodySetup
BodySetupCore pointer that this instance is initialized from
uint8:  1
bOverrideMass
If true, mass will not be automatically computed and you must set it directly
uint8:  1
bSimulatePhysics
If true, this body will use simulation.
uint8: 1
bStartAwake
If object should start awake, or if it should initially be sleeping
uint8:  1
bUpdateKinematicFromSimulation
When kinematic, whether the actor transform should be updated as a result of movement in the simulation, rather than immediately whenever a target transform is set.
uint8: 1
bUpdateMassWhenScaleChanges
If true, it will update mass when scale change
